Netarts Bay is a shallow, temperate, tidal lagoon located on the northern coast of Oregon and the site of the Whiskey Creek Shellfish Hatchery (WCSH). Data collected with an autonomous continuous flow-through system installed at WCSH capable of high-resolution (1 Hz) partial pressure of aqueous CO2 (pCO2) and hourly total dissolved

Ninokawa, Kristen Elsmore, Brian Gaylord First published: 31 March 2021 https://doi.org/10.1111/gcb.15594 Abstract Global‐scale ocean acidification has spurred interest in the capacity of seagrass ecosystems to increase seawater pH within
Highlights • Spatial and temporal variation in estuarine acidification cause severe biological responses. • Extreme low saturation state and duration of exposure cause pteropod shell dissolution. • Changing estuarine conditions cause cumulative stress that was used to generate stress index. • Compensatory mechanisms allow pelagic calcifiers to persist in extreme
Krill are abundant and ecologically important zooplankton that inhabit dynamic environments characterized by strong natural variability, but global ocean change is shifting the range of conditions that they experience. Laboratory tests reveal that krill are sensitive to ocean acidification despite residing in naturally low pH areas, showing the importance of
Shelled pteropods are widely regarded as bioindicators for ocean acidification, because their fragile aragonite shells are susceptible to increasing ocean acidity. While short-term incubations have demonstrated that pteropod calcification is negatively impacted by ocean acidification, we know little about net calcification in response to varying ocean conditions in natural populations.
